Kerr–Newman metric

Ever wondered how a spinning charged black hole defies our everyday physics?

Imagine a spinning top that suddenly starts glowing and warping space around it; this is what happens in the universe with a rotating charged black hole.

The Kerr-Newman metric helps us understand how space and time are twisted by the spinning and electric charge of a black hole, much like the top's motion affects its surroundings.

Example

Consider a black hole spinning at 90% the speed of light, with a charge equivalent to 10²0 electrons, warping space around it.

Remember this

The Kerr-Newman metric is the formula that describes this cosmic dance of spinning, charged black holes.
